Masterscan D-70 user’s manual

Disclaimers and Notices

The following information must be read and understood by users of the Sonatest Masterscan D-70

ultrasonic flaw detector and thickness gauge. Failure to follow these instructions can lead to serious

errors in test results or damage to the flaw detector. Decisions based on erroneous results can lead

to property damage, personal injury or death. Anyone using this instrument should be fully qualified

by their organization in the theory and practice of ultrasonic testing, or under the direct supervision

of such a person.

General Warnings

Proper use of the ultrasonic test equipment requires four essential elements:

Knowledge of the specific tests or inspections and applicable test equipment.

Selection of the correct test equipment based on knowledge of the application.

Competent training of the instrument operator.

This user’s guide provides instruction in the basic operation of the Masterscan D-70 flaw

detector. In addition to the methods included, many other factors can affect the use of

this flaw detector. Specific information regarding these factors are beyond the scope of

this manual. The user should refer to appropriate textbooks on the subject of ultrasonic

testing and thickness gauging for more detailed information.

Specific Warnings

The Masterscan D-70 contains a high-energy, precision pulser allowing optimum test

results to be obtained by matching the pulse width to the probe characteristics. This

circuitry may be damaged by voltage spikes. It is recommended that the instrument be

switched off, or the pulser stopped (by pressing the

[Freeze/Peak]

key) before changing

probes.

Operator Training

Operators must receive adequate training before using this ultrasonic flaw detector.

Operators must be trained in general ultrasonic testing procedures, and in the set-up and

performance required by each specific test or inspection. Operators must understand: Sound

wave propagation theory.

Must understand the effects of the velocity of sound in the test material.

Must know the behaviour of the sound wave at the interface of two different materials.

Must have an understanding of Sound wave spread and mode conversion.

More specific information about operator training, qualification, certification and test specifications

can be obtained from technical societies, industry groups and government agencies.

Masterscan D-70 user’s manual

Testing Limitations

In ultrasonic testing, information is obtained only from within the confines of the sound beam as it

propagates into the test material. Operators must exercise great caution when making inferences

about the nature of the test material outside the limits of the sound beam. The condition of

materials can vary significantly and the results can be erratic if operators don’t exercise good

judgment.

Critical Operating Factors

The following procedures must be observed by all users of the Masterscan D-70 in order to obtain

proper, accurate and consistent results.

Calibration of the Sound Velocity

An ultrasonic flaw detector operates on the principle of measuring the time of flight of a burst of high

frequency sound through the test piece, as well as evaluating the amplitude of reflected or

transmitted echoes. The sound velocity of the test piece multiplies this time in order to obtain an

accurate distance or thickness reading. Since the actual sound velocity in materials can vary from the

published values, the best result is obtained when the instrument is calibrated on a reference block

made from the same material as the test piece. This block should be flat, smooth and as thick as the

maximum thickness expected of the test piece.

Users should also be aware that the sound velocity might not be constant throughout the test piece

due to effects such as heat-treating. This must be taken into consideration when evaluating the

results of ultrasonic thickness testing. The calibration should always be checked after testing to

minimize errors.

Transducer (Probe) Zero Procedure

The transducer calibration procedures must be performed as described in this manual. The

calibration block must be clean, in good condition and free of noticeable wear. Failure to perform

the transducer zero and calibration procedure will cause inaccurate thickness readings.

Flaw Detection Calibration

When performing a flaw detection test, it is important to note that the amplitude of indications is

not only related to the size of the discontinuity; the depth of a discontinuity below the test piece

surface will also have an effect on the amplitude due to characteristics of the sound beam spread

and near field zone of the transducer. In addition, the characteristics of the discontinuity such as

orientation and classification can alter the expected amplitude response. For these reasons,

calibration should be performed on test blocks made of the same material as the test piece with

artificial discontinuities within the range of size and depth in the material to be detected. The user is

again cautioned to refer to reference books which are beyond the scope of this manual.

Masterscan D-70 user’s manual

Effects of Temperature on Calibration

The sound velocity in test pieces and the transducer wear face changes with temperature variations.

All calibrations should be performed on site with test blocks at or near the same temperature as that

expected on the test piece, to minimize errors.

Transducer Condition

The transducer used for testing must be in a good condition, without noticeable wear of the front

surface. The specified range of the transducer must encompass the complete range of the thickness

to be tested and/or the types of discontinuities to be investigated. The temperature of the material

to be tested must be within the transducer’s specified temperature range.

Use of Couplant

Operators must be familiar with the use of ultrasonic couplant. Testing skills must be developed so

that couplant is used and applied in a consistent manner to eliminate variations in couplant thickness

which can cause errors and inaccurate readings. Calibration and actual testing should be performed

under similar coupling conditions, using a minimum amount of couplant and applying consistent

pressure to the transducer
